The getMBeanInfo call fails if and only if:
- Server runs over Mustang build 37 or over
- Client runs over Tiger (used Update 5 build 2)

The tnameserv has been started with Tiger.
The stack trace is stored in file client.out.
It starts that way:

Jun 20, 2005 6:08:41 PM com.sun.corba.se.impl.encoding.CDRInputStream_1_0 read_value
WARNING: "IOP00810257: (MARSHAL) Could not find class"
org.omg.CORBA.MARSHAL: vmcid: SUN minor code: 257 completed: Maybe
at com.sun.corba.se.impl.logging.ORBUtilSystemException.couldNotFindClass(ORBUtilSystemException.java:7756)

BUT all goes fine if:
- Server runs over Tiger and Client over Mustang
- Server and Client run both over Tiger or both over Mustang
- a Mustang build 36 is used for Server when Client is over Tiger

==> that interoperability regression started with Mustang b37.

In order to reproduce, use the attached zip file that contains all java and class files and follow the steps as listed:
        In a first shell, do:
        tnameserv -ORBInitialPort 9999
        
        In a second shell, do:
        java Server
        
        In a third shell, do:
        java Client
